SPECIFXCATION forming part of Letters Patent No. 741,086, dated October 13, 1903. Application filed January 18, 1901. Serial No. 43,763; (No model.)

To all whom it may concern:

Be it known that I, SAMUEL J WEBB, a citizen of the United States, residing at Minden, in the parish of Webster and State of Louisiana, have invented certain new and useful Improvements in Rotary Fluid-Motors, of.

which the following is a specification.

My invention relates to apparatus for use to receive motion from or transmit it to fluids of any character; and my invention consists of a casing provided with two pairs of ribbed cylinders constructed, arranged, and operating to rotate under the pressure or impact of a motor fluid, as well as to forcibly propel a fluid when the cylinders are turned, as fully set forth hereinafter and illustrated in the accompanying drawings, in Which-- Figure 1 is a sectional elevation of an apparatus embodying my invention. Fig. 2 ,is' a sectional plan; Fig. 3, an end view; Fig. 4, a View showing a modification; Fig. 5, a sectional View illustrating one construction of the ribbed cylinders.

The outer casing A is preferably. cylindrical, and the heads or ends have bearings for four parallel shafts 1 2 3 4, upon each of which is mounted a ribbed or toothed cylin- Ger.

Each pair of cylinders '13 C has teeth 5 5, which mesh with each other in the same manner as ordinary gears; but the shafts 1 and 2 and 3 and 4 are farther apart than the shafts 1 and 3 and 2 and at, so that the ends of the ribs either meet, as in Fig. 5, or, as in Fig. .1, the end or edge of each rib may be formed into minor ribs or teeth 6 6 of less depth than the main teeth, and these minor teeth of the opposite cylinders B and G will mesh, al-

though the main portions of the teeth do not interlock.

Between the heads of the casing A and the ends of the cylinders are annular packings,

casing is an outlet or exhaust port 11 As a result of this arrangement any pressure in the casing A upon exposed sides of the ribs 5 5 at the points where the ends of the ribs come together exerts its energy upon a greater area than at the points where the ribs of one cylinder fully enter between those of the other, so that there is a constant pressure tending to turn the cylinders in the direction the heads of the casing through which the shafts extend.

In the modification shown in Fig. 5 the end of each rib 5 is grooved to receive a suitable packing-strip 15.

While the cylinders may be of cast metal, with teeth or ribs integral with the bodies 4, it is preferable for some reasons and in some cases to use a material which will not cause any noise or rattling from the contact of opposing ribs. I therefore in such case form the body c of thepylinder with radial flan ges 16 and mold or cast on this body a facing b, of vulcanized rubber or other material, as shown in Fig. 4.

When it is desired to secure the-impact o the motor fluid, the port so may be of such shape that the fluid will be projected as a forcible jet against the ribs of the opposite cylinders, and the port may be controlled by a blade-valve 19, with a stem passing through a packing-box, so that the valve may be adjusted to regulate the size of the jet, and there may be a port and valve opposite each pair of cylinders.

The apparatus above described may be used in connection with any fluid under pressure as amotor, or it may be positively driven to receive a fluid and forcibly expel thesame asapump. 7 Q 1 lNithout limiting myself tothe-precise construction shown and described, I claim-- 1. The combination with a casing having inlet and outlet ports, of four cylinders with radial teeth or ribs, the ribs of each cylinder meshing or interlocking with those of one of of the ribs of the other cylinder, with adjustable bearings for the shafts of two of the diagonally opposite cylinders, substantially as set forth.

3. The combination with a casing having inlet and outlet ports, of four cylinders with radial teeth or ribs, the ribs of each cylinder meshing or interlocking with those of one of the adjacent cylinders but meeting the edges of the ribs of the other cylinder, with annular packings between the ends of the cylinders and the heads of the casing, substantially as set forth.

4. The combination with a casing having inlet and outlet ports, of four cylinders with radial teeth or ribs, the ribs of each cylinder meshing or interlocking with those of one of the adjacent cylinders but meeting the edges of the ribs of the other cylinder, a drivingshaft, and gearing between the latter and the shaft of one cylinder of each pair, substantially as set forth.

5. The combination with a casing having inlet and outlet ports, of two pairs of cylinders with radial teeth or ribs having minor teeth at their edges, the main teeth of each pair of cylinders interlocking While the minor teeth of each cylinder of a pair interlock with the minor teeth of the respectively opposite cylinder of the other pair, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL J. WEBB.
